Abstract (en)
[origin: WO2019033170A1] The present disclosure relates to a tracking system for tracking the position and orientation of an object in an environment, the tracking system including: (a) a tracking base positioned in the environment; (b) a tracking target mountable to the object, wherein in use the tracking base is linked to the tracking target by: (i) a bidirectional light beam transmitted therebetween; and, (ii) a unidirectional light beam transmitted therebetween, said unidirectional light beam parallel to the bidirectional light beam; and, (c) at least one controller configured to determine a roll angle of the tracking target relative to the tracking base, the roll angle determined at least in part by signals received from a sensor housed in at least one of the tracking base and the tracking target that detects the unidirectional light beam.
